OSCILLAIING- WIND-MOTOR.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed January 29, 1908. Serial No. 413,191.

To all whom it may concern:

Be it known that I, DANIEL DUNCAN Mo- INTYRE, a citizen of the UnitedStates, residing at Bucklin, in the county of Ford and State of Kansas,have invented a new and useful Improvement in Oscillating I/Vind-Motors, of which the following is a specification.

My invention is in the nature of a wind motor of that type in which anoscillating frame is arranged upon a horizontal axis and is providedwith blades that are alternately turned flatwise and edgewise to thewind and the force of the wind is applied directly to produce theoscillation of said frame.

The invention consists in the novel construction and arrangement ofparts for shifting the blades as hereinafter described in connectionwith the drawings, in which Figure 1 is a side elevation. Fig. 2 a rearelevation. Fig. 3 is a cross section on line 33 of Fig. 2, and Fig. 4 isa perspective detail partly in section of the upper end of thesupporting standard and rocking crank shaft.

In the drawing, A is a frame composed of two vertical and parallel sidebars connected by two cross bars a 11. Between the lower extended endsof the side bars is rigidly connected the horizontal rock shaft B, whoseends are squared and fitted by nuts and plates to the side bars so thatsaid shaft cannot turn in the side bars but has a strong and rigidconnection therewith. This shaft is journaled in bearings b 1) upon thetop of a collar'C attached to a tube section 0, Fig. 4, which enters thetop of a pipe D which forms the supporting standard or mast on which mymotor is carried. At a point between the bearings b b the shaft is bentinto a crank d, to which is attached the connecting rod 29 of a pump orother mechanism to be operated, said cormecting rod passing down throughthe collar 0 and the tubular standard to a suitable point below.

To the lower ends of the side bars are attached two heavy weights E. Thewind motor is designed to oscillate about the axis of shaft B, from anearly horizontal position to a verticalposition. The wind effects thedirect deflection of the frame backward and away from the wind, as seenin Fig. 1, in dotted lines, and the weights E restore the frame to thevertical position again.

To render the above described action automatic and continuous, twoseries of vertical blades F F are hinged at one longitudinal edge e tothe cross bars of the frame and to the outer or swinging edge of eachseries of bladesa transverse bar 0 is loosely coupled so that when thisbar is moved longitudinally in one direction it will turn the bladesflat face to the wind, and when moved in the other direction it willturn the blades edgewise to the wind. When the blades have their fiatfaces to the wind the forceof the latter tilts the whole frame towardthe horizontal position and when the blades are turned edge wise to thewind, they then offer practically no resistance to the wind and theweights E bring the frame back to the vertical position again.

To make the change in the plane of the blades at the end of each stroke,a forked lever G has its two branches fulcrurned at f 7' to off-settingsupports 8 s on the lower cross bar. The lower branched ends of thislever are connected by link bars g g with the two transverse bars 0 0and the upper end of said lever is provided with a weight h. WVhen themain frame is vertical the lever G is vertical and the blades are flatface to the wind. Now when the main frame swings rearwardl r anddownwardly toward the horizontai, from the pressure of the wind, theweight it swings away from the main frame from the combined influencesof gravity and inertia and this causes the lower branched ends of thelever G to approach the main frame and turn the free edges of the bladesedge wise to the wind. As soon as this takes place, the blades no longerfeeling the pressure of the wind, the operating weights E E restore theframe to the vertical position. As the frame swings to the verticalposition the weight k swings toward the frame from its inertia and thelower forked ends close the blades fiat wise to the wind for arepetition of the former action. In this way the oscillations of themain frame are made continuous by the automatic action of the shiftingweight.

. To throw the motor out of action, the blades are adjusted and heldedge wise to the wind by means of a rope 1' which connects with suitableguide eyes down beside or through the collar and hollow verticalstandard.

It will be seen that the lower forked ends of the lever are spread aparta considerable distance which gives a long axial fulcrum for the lever,which reduces wear and looseness the shifting lever and extends throughI and maintains the true plane of oscillation of the lever with aminimum of friction and moving parts, the lower end of one branch beingconnected to and operating the half of the blades on one side of themiddle line and the lower end of the other branch operating the half ofthe blades on the other side of the middle line.

I claim 1. An oscillating wind motor comprising an u right frame havinga horizontal axis of oscil ation and hinged blades and a shifting leverconstructed with branched and spaced apart lower ends fulcrumed to theupright frame, means for connecting these branched ends to the bladesand a weight mounted upon the upper end of said lever.

2, An oscillating wind motor comprising an upright frame having ahorizontal axis of oscillation and hinged blades and a shifting leverconstructed with branched and spaced apart lower ends fulcrumed to themain frame, means for connecting these branched ends to the blades and aweight mounted upon the upper end of said lever, the blades beingarranged in two groups with separate connecting bars and the twobranched ends of the lever being separately connected to the two groups.
